Ukrainian President Volodymyr Zelenskiy and other Ukrainian officials deny reports that Russian forces have captured the eastern Ukrainian city of Kostiantynivka. The claims, attributed to external reporting outlets, assert that Russian troops have taken control of the town, but Ukrainian sources reject those characterizations and do not confirm any change in control.

Across the sources provided, the key point is that the alleged Russian takeover is disputed. The denial is presented as a direct response to circulating assertions that Kostiantynivka has fallen under Russian control. No source supplied here provides independent verification, figures, or details about battlefield control from a neutral party.

As presented, the situation remains contested, with Ukrainian officials maintaining that Russian forces have not secured the city. The reports highlight the ongoing information conflict surrounding territorial claims in eastern Ukraine, where both sides often contest developments on the ground.
